Lest we forget...

10mm outside diameter. Seem them on the couple of 69 510’s I’ve worked on recently as well doing the same duty.

sometimes its hard to see when the stamped numbers are full of "nasty". Just count the teeth if you can't find it.

The holes are likely a weight saving feature. Or a way to tease you. You look in there and realize there is space to squirrel things away, but you realize can’t get there from here…. Someone was a hero when they suggested using that space for tools and doing away with the behind seat storage.

The bumper mounts got bigger, the doors got bigger intrusion bars, the hazard switch and HCP’s grew illumination, the gathering storm of safety and emissions requirements was just gathering steam.

You’re missing the internal safety bar that is normally inside that door. It is attached with three bolts through those holes on this end.

Well, I stand corrected. And thinking about it after having driven this trans for many miles, first is not as low as I thought. Thanks for setting that straight

Something about “Thou shalt not covet thy neighbor’s Datsun….” comes to mind, but… I’m coveting like crazy here. Nice find indeed!

These late 77-78 latches are different than the earlier ones, but the single most powerful thing I done that often changes a door that won’t latch into one that latches easily is to lubricate the mechanism. It HAS to rotate freely or it will have trouble getting to the “2nd stage” latched all the way position.

About the only thing I’m putting on the bottom of my Datsun’s now is a pro quality 2-part “truck bed liner” like Raptor. It has proven itself on the bottom of several heavily driven cars in my sphere of influence…. As with anything you apply to your bottom, proper prep and attention to detail are the key to staying stuck for a long long time. My first experience with this stuff in the bed of my various ford 1/2 tons, and with all the scrap metal and datsun junk I have abused those boxes with the ONLY damage I have ever done to the coating is with a single small chip that I caused with an sharp engine block corner crashing into the deck one day when “putting” (more like tossing…) it back there. With the current truck we are 7 years in and the coating looks new, other than not being shiny and black anymore.

Yes this is always an option. I haven’t measured it, but the total adjustment in the two slots on the dizzy base seem to be about the rotation distance between the 6 towers. The only issue is assigning wire lengths that “fit” well with your new dizzy ‘TDC” position for each plug.

Datsun stud pattern is 4 x 114.3mm. What bolt pattern are the wheels you’re looking at? +25mm wheels will require spacers to clear the tire away from the strut, maybe 15mm (5/8) is enough spacer.

I can beat totalZ and ebay pricing. Send me PM and we’ll discuss

Glass beads will work, as will a wire brush. Brass or SS. Cleans up aluminum very nicely. Then an oil based sealer like Gibbs to preserve the finish. I’ve even used the cast aluminum caliper paint from VHT.

How many times have we heard “the power is in the head”. Still true. Cam, lift, porting. Make’r flow like a hurricane!

Here is my tool, just for completeness and give others ideas.

Flat blade screw driver and hammer has always worked for me. Tap one tab, then next, it comes off. I did make a tool to help, which it does, especially when the tank is still in the car. Based on a short 2” steel pipe nipple that I welded little tabs on that hit on those four little tabs. Then added a bar and 17mm nut welded in the center to put a socket or wrench on. Great if you have a welder. Interesting that the Honda ring is so similar. Good find.

You know, we all do it, browse through some marketplace, ebay, craigslist, Kijiji, looking for Datsun goodies, sometimes you find something interesting and you put it in your shopping cart for later. Gives you a chance to ask that eternal question, “Need” or “Want”…. Makes you feel like you’re in control of your purchases. Right… Anyway. Well I’ve done that on ebay lately, put a couple if items in my cart for “later”, A headliner for my latest 510 project, some key blanks for Z locks, etc. Both items were simple purchase, not auctions. Well, the key blanks were in the cart first and by themselves for about a week when I get this un-expected notification from ebay that the seller has given me an a special discount offer of 10% off if I agree to buy in the next little while. Interesting! Decided not to push the button just yet. Then after adding the head liner, about 3 days later I get a similar message about a discount offer of 11%! This one I jumped on, as I was just waiting to decide who to buy it from. (Goliners, respected well know Datsun headliner vendor, not a scam) So next time you want to buy something on Ebay, and you can wait a few days, put it in your cart and let it “ferment” there for a few days and see what happens! Maybe you’ll get a discount too!

The thing that freaked me out was the day I discovered the hatch lock striker bar isn’t in the center of the slam panel. The release button up on the hatch deck is in the middle, but not the actual catch Sometimes we assume symmetry where none exists.

Never seen a published solution for using an extrusion on an SU manifold, but I bet it’s been done. Heat wise, I’d be tempted not to mount the rail to the head. There are plenty of un-used mounting points on the balance tube that I would likely press into service. The stock fuel rail return line has a tiny orifice hole in the tip where the 3/16 hose gets clamped on, this is the stock pressure regulation. I’m hoping you plan on running some sort of regulator on your system on the return side of your rail.

Or seriously, some Killmat or Dynamat foil with butyl backing sound insulation sheeting provides excellent adhesion and permanent seal. Put lots of it down while you’re at it.

Wasn’t there some big Z shin-dig going on earlier this year in Colorado Springs? Some little party called ZCON or something? Must be a few Z people hiding under the bushes you could rustle up.

The “thing” on the left looks to me to be an aftermarket temperature switch, the kind of thing you use to trigger an electric fan on the rad. When the temp gets to the right temp that spade terminal is connected to ground, which you use to trigger a relay to turn on the fan. The 1/4 spade connector is the type of thing I’d expect to find on an aftermarket switch of that type.

Sean I have a bunch of these. I’ll send you a good one. Send me a PM and we can discuss. I’ve had several that stick like yours, it was a pain to take it apart and file in the just the right places to free it up. It was also very unclear as to how this stickiness developed in the first place.
